This study presents for the first time the deformation time series for the cities of Volos and Igoumenitsa for the time span 2001 – 2010, aiming at integrating these results with geology towards proposing mitigation measures to suppress risks for assets and the local population.

Specifically, we present ground velocities for the cities of Volos and Igoumenitsa, Greece, as obtained from the analysis of Synthetic Aperture Radar (SAR) imagery. Time series analysis of Radar data is suitable for mapping deformation in urban environments with millimeter level accuracy. In our study, displacement rates have been measured using two frames, one for each city, via the processing of ASAR/ENVISAT. The data have been processed with the Persistent Scatterrers (PS) and Small Baseline Subset (SBAS) techniques using the StaMPS software. The local displacement patterns revealed are mainly associated with anthropogenic processes.

At last, we investigate the potential correlation of InSAR measurements with geology and hydrological network. This is essential both for the validation and the comprehensive interpretation of the underlying processes, anthropogenic or physical.
